Partial-Resolution Image Segmentation for Motion Artifact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods to reduce motion artifacts in television displays, such as increasing frame rate, result in significant increases in processing bandwidth and system complexity, leading to increased costs and complexity in circuitry design and manufacturing.
Innovation Solution
The method involves extracting and calculating partial-resolution images, specifically half-resolution images with a checkerboard pattern, to create complementary images that are displayed at different times, effectively doubling the frame rate without doubling the bandwidth.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the frame rate is increased to reduce motion artifacts, then motion artifacts are reduced, but processing bandwidth and system complexity increase significantly
Solution Approach 1:
The patent divides the full-resolution image into multiple partial-resolution images (e.g., four quarter-resolution images). Each partial image covers a different portion of the full image, allowing the system to process and display fewer pixels per frame while maintaining the perceived frame rate. This segmentation reduces the processing bandwidth required for each individual frame.
Solution Approach 2:
The patent transitions from processing complete full-resolution frames to processing partial-resolution segments. By displaying multiple partial images in sequence rather than complete frames, the system effectively increases the temporal resolution (frame rate perception) without proportionally increasing the spatial processing burden, thus reducing motion artifacts without doubling bandwidth requirements.
2Object-affected harmful factors
If the frame rate is doubled to reduce motion artifacts, then motion artifacts are reduced, but circuitry costs and manufacturing complexity increase
Solution Approach 1:
By segmenting the full-resolution image into multiple partial-resolution images that can be processed independently, the patent reduces the computational load on downstream video processing circuitry. This allows existing circuitry to handle the processed partial images without requiring expensive upgrades to support doubled bandwidth, thereby reducing manufacturing costs.
Solution Approach 2:
The patent processes only the necessary portions of the image at high resolution rather than processing entire frames at full resolution. By calculating and displaying partial-resolution images selectively, the system achieves the motion artifact reduction effect without requiring full-bandwidth processing circuitry, thus lowering manufacturing complexity and costs.
3Object-affected harmful factors
If full-resolution images are processed to double the frame rate, then motion artifacts are reduced, but processing bandwidth doubles
Solution Approach 1:
The patent segments the full-resolution image into multiple partial-resolution images, each containing only a portion of the original pixel data. By processing and displaying these partial images in sequence rather than complete frames, the system reduces the bandwidth required for processing while maintaining the temporal density needed to reduce motion artifacts.
Solution Approach 2:
The patent extracts only the necessary partial-resolution portions from full-resolution images rather than processing entire frames. By taking out and processing only the relevant segments needed to reduce motion artifacts, the system avoids the bandwidth overhead of processing complete high-resolution frames, thus reducing processing bandwidth requirements.

AI summary
A method for reducing motion artifacts and the systems for implementing the same are provided. The method includes receiving a full-resolution image at a first time point; extracting a first partial-resolution image from the full-resolution image; and calculating a second partial-resolution image for a second time point after the first time point. The first and the second partial-resolution images are complementary.
